Day 3 Surface Map


Heavy rains still continue to impact portions of the WGRFC area this morning. An area of showers and thunderstorms is currently moving over portions of southeast Texas...mainly affecting the lower Trinity and Neches River systems. Rainfall amounts are averaging 1 to 2 inches per hour, and this trend should continue through noon. Another area of showers and thunderstorms stretches from West Texas towards the Oklahoma. Rainfall amounts associated with this activity are averaging less than 1 inch per hour. Over the past several hours, some minor rises occurred across the San Antonio River system, however no significant river flooding has been reported.

Overall, our region continues to be under a southwesterly upper air flow which will keep our weather unsettled through tomorrow morning, as an upper level low approaches from the west. Ahead of this low, showers and thunderstorms are expected to develop along and east of the dry line. During the afternoon and evening hours, heavy rainfall with the possibility of severe weather is expected over a good part of Texas and Louisiana through tomorrow. Some additional minor rises are expected across some river basins across southeast Texas. However, widespread moderate or major flooding is not expected.

By late tonight the low pressure system will move over Kansas, with dry air moving into Texas from the west. This will cause the rainfall to diminish late tonight and tomorrow over most of the area except for Texas Gulf coastal region. Thereafter, a weak ridge of high pressure will bring dry weather for most of the region for tomorrow and Sunday morning.

By Sunday a new low pressure system is forecast to develop and move toward the four corners region. This will bring mixed precipitation over northern New Mexico and southern Colorado Sunday and Monday. And over Texas there will be another chance for showers and thunderstorms later Sunday, but will be more likely over east Texas and Louisiana on Monday.

By Monday night another low pressure system is forecast to move over Oklahoma. Some wrap-around rainfall is possible across northern Texas late Monday into Tuesday.

5 Day Total Rainfall Forecast

Moderate or worse drought conditions continue across parts of New Mexico and Texas. In Texas, about a third of the state is experiencing moderate or worse drought (35%), and about 9% has extreme to exceptional drought conditions. In New Mexico, a little over half of the state is experiencing moderate or worse drought (58%). Lake levels in the extreme drought areas of Texas are at or near historical lows for this time of year. Recent precipitation events have brought drought relief to parts of far west Texas, south Texas and roughly the southeast third of the state. The rainfall expected over the next five days over the WGRFC area could produce some runoff over east central and northeast Texas where the heaviest rainfall is forecast. No significant runoff is expected over the remainder of the WGRFC area.
